1. A display substrate, comprising: a display area and a periphery area surrounding the display area; the display substrate further comprising:
a signal line, wherein the signal line comprises a first section located at the periphery area;
a plurality of basic spacers, wherein at least a part of the plurality of basic spacers are located at the display area;
a plurality of compensation spacers disposed at a first periphery area, wherein an orthographic projection of the first periphery area onto a base of the display substrate at least partially overlaps with an orthographic projection of a side face of the first section onto the base; a layout density of the plurality of compensation spacers is greater than a layout density of the plurality of basic spacers; and
an encapsulation structure, wherein the encapsulation structure comprises an organic encapsulation layer and an inorganic encapsulation layer arranged in a stack, the organic encapsulation layer and the inorganic encapsulation layer covers the plurality of compensation spacers.
